We studied the vitamin C status of smokers and nonsmokers among staff members of our university in 1982. This paper describes the results from the 1983-85 studies. Plasma vitamin C levels (M +/- SD, mg/dl) from smokers and nonsmokers, respectively, were as follows: 0.49 +/- 0.15 (n = 51) and 0.72 +/- 0.23 (n = 73) in 1983, 0.56 +/- 0.13 (n = 48) and 0.84 +/- 0.21 (n = 88) in 1984, and 0.52 +/- 0.15 (n = 56) and 0.86 +/- 0.24 (n = 93) in 1985. The differences between smokers and nonsmokers are all highly significant. Urinary vitamin C levels (M +/- SD, mg/dl) from smokers and nonsmokers, respectively, were 1.8 +/- 0.6 and 2.6 +/- 0.9 in 1983 and 2.0 +/- 0.7 and 2.9 +/- 1.0 in 1984. These differences between the two groups are also highly significant. Both groups were similar in age, height, weight, general health parameters, and vegetable and fruit consumption. Plasma and urinary vitamin C levels were significantly higher in smokers taking vitamin C supplement than in those not taking vitamin C supplement.
1982年，我们研究了我校教职工中吸烟者和非吸烟者的维生素C状况。本文描述了1983 - 1985年研究的结果。吸烟者和非吸烟者的血浆维生素C水平（均值±标准差，mg/dl）分别如下：1983年为0.49±0.15（n = 51）和0.72±0.23（n = 73），1984年为0.56±0.13（n = 48）和0.84±0.21（n = 88），1985年为0.52±0.15（n = 56）和0.86±0.24（n = 93）。吸烟者和非吸烟者之间的差异均具有高度显著性。吸烟者和非吸烟者的尿维生素C水平（均值±标准差，mg/dl）在1983年分别为1.8±0.6和2.6±0.9，1984年分别为2.0±0.7和2.9±1.0。两组之间的这些差异也具有高度显著性。两组在年龄、身高、体重、一般健康参数以及蔬菜和水果摄入量方面相似。服用维生素C补充剂的吸烟者的血浆和尿维生素C水平显著高于未服用维生素C补充剂的吸烟者。
